I always thought these were gimmicky. But I got one for Christmas and liked it so much I bought 2 more. I have all hard flooring, no carpets, and 2 dogs, a cat, and two birds that all contribute to mess. So I had to sweep everyday or I'd get those pet-hair tubleweeds blowing around. Having to sweep all the time I get lazy and let it go; or when I do it I spend an hour or 2 sweeping or vacuuming. These robots save me hours of time and get the job done better because they are relentless. I set them on a schedule and they do it everyday completely. I have one robot that I manually have to empty the cup everyday. He's in the bedroom, since I'm in that room every day that's convenient enough and only takes 2 minutes. I bought an i3+ and an i4+, they self empty and I have to change the bag about once every 2-4 months. I don't mind the cost of the vacuum bags because they give me so many hours of my time back. The first one I got is the little guy. The little guy's name is Finigan. Finigan isn't too smart. He vacuums in a random pattern. I started with him in the main part of the house. He did a great job but his battery usually ran out before he considered himself done. So the space is a bit more then he likes. He did a great job though. But I loved it so much I got more to cover the whole house and moved him to the smaller bedroom area. In the bedroom suite (bedroom + bathroom~350sq ft), he spends about 45 minutes zipping around to cover everything. When his battery is low he docks himself. I have to empty his cup everyday. At first his cup was usually about 3/4 full to full. The first day it filled and he stopped. I had to empty it and re-start him. After a few months of daily vacuuming, the cup is about 1/4 full each day. So I switched him to a MWF schedule. He's still about 1/4 to 1/2 full each use. He even goes under the bed and keeps that clean. It's really great. The i3+ is Dixie. Dixie does the downstairs. Dixie is smart. She goes in straight line patterns and covers the entire space using a very planned straight line methodical routine. The first day she poked around learning. It was about 1.5 hours. After that, the entire job was planned out and she did the whole thing in about 45 minutes. She has no problem when certain doors are opened vs closed. When it's open, she goes in and vacuums. If it's closed, she skips it. Her cleaning time varies from about 45 minutes to 1hr 15minutes depending on whether the extra rooms are included (doors open vs closed). She drives back to her base when done and docks. And the base sucks out what she collected. I love the base, it means I do not have to tend to her everyday. I actually only need to change the bag about every 3-4 months. There's not a lot going on downstairs. The litter box is there and so the cat pays visits. But we aren't down there daily tracking things around. Thanks to Dixie, there's no fur balls, hair-tumbleweeds, dust, or dirt. Always a nice clean floor. It's awesome. Her map in the app shows where she found 'extra' dirt. Usually right in front of the litter box. It's so awesome not having to sweep up litter daily. I have her on a MWF schedule too and that is more than enough to keep the place clean. I recently got Nick, an i4+ for the upstairs. He's quieter. He's like Dixie in is planning and map reporting, so he's smart. It's very cool. He also gets the job done quickly. First day was like 1.5 hours learning. Now he's done in 50 minutes. The base sucks everything out so I don't have to tend to him as much as Finigan. He's in the main part of the house and it gets the most dirty. The dogs spend all there time here. The cat is up here most of the time. And we have two birds who send seeds everywhere. It's amazing how far from the cage those birds can flick seeds. And their feathers and drift everywhere too. Nick takes care of all that. I do need to manually get under the couch and behind and under furniture which I do once every month or so. But this robot is awesome. Saves me the day in and day out sweeping and vacuuming. Having robots spend 3+ robot labor hours each day vacuuming is an awesome human labor saver. Once they've hit the whole house for a month or two I'm able to step them back to MWF schedules. Their brushes do a great job in the corners, better than me sweeping or vacuuming; mostly because they hit those corners every day and spend the time swirling that brush to work on it. That constant day in day out effort pays off over time. I really can't imagine going back to manually doing this. I look back at the hours I spent doing it thinking that was Neanderthal days. I look forward to telling my grand kids how I used to walk to school uphill in the snow everyday, dial rotary phones, select music off of CD's I had to manually put into a machine, and now, that I spent hours sweeping the floors in the good old days.

This is a great product. I purchased this product back in 2022 and never wrote a review until my grandson asked me too so here we go. I named my vacuum Hank so when I use the word Hank, I’m referring to my vacuum. Hank does an amazing job. Weather is on stone floor, hardwood floor or rug. The amount of dust he picks up blows my mind all the time. I always thought my house is so clean and then Hank came along. I love the fact that it maps that you can set a set schedule and that schedule definitely stays intact. I had one problem with it. I was able to reboot it, and Hank works like a champ once again if I had to purchase this item again it would definitely be a no-brainer to me. This is a great product; bravo to the creators.

UPDATE: After owning this sweeper and learning the quirks I changed my star rating from a 1 to a 4 star. If you have animals in the house their hair wraps around wheels, rollers, and anywhere you wouldn't think of! So the hair will cause the sweeper not to work. We actually had to watch you tube videos about this sweeper to figure out why the sweeper would stop working. We also had the sweeper vacuum every day and figured three days a week works to maintain and we could use our old vacuum in-between the days it wasn't working as needed. This was a three month process to figure this sweeper out. This sweeper is a great idea but O.M.G. it just doesn't work! My wife uses a sweeper everyday and she thought how nice it would be to have a little assistance. We do have two dogs so using a sweeper is a must daily so we purchased the iRobot to vacuum at night while we are sleeping so we wake up to clean floors! It worked briefly for two weeks and then it just stopped working. There were continuous problems telling us to clean the brushes, so we removed the brushes and saw some dog hair and removed it. Next night it stopped working saying something else needed cleaned and we did that and the next night it stopped and said change the filter! So we purchased filters for a two week old vacuum and changed the filter. Then it was something with the brushes and said change brushes! CHANGE BRUSHES!?! ITS TWO WEEKS OLD!! So you will have to purchase filters, vacuum bags, two types of brushes and it says the brushes last 250 hours but had to change them only after two weeks. This vacuum was expensive to start with and if I would of known that we would be replacing parts continously and often for the life of this machine I would not of made this purchase. I only have to guess it's defective because if this is normal for their product they would be out of business and wouldn't sell any of these units. My opinion at this time is stay away from purchasing this vacuum. Our vacuum just doesn't work.

I upgraded from an off brand vacuum that cost less than $100 with coupons. At first, we were thrilled. It picked up better than the other vacuum and what’s not to love about the bin automatically emptying the vacuum? Now we’ve owned this thing for about 7 months and I believe it to be a waste of a few hundred bucks. It has stopped auto emptying. I’ve done all the trouble shooting I can find online. So now we have to hit to button to get it to empty, but only when the button is available on the app, which isn’t all the time. There’s a whole other fix for each time that happens, if you feel like spending 10-15 minutes doing it, which in my opinion I’d rather spend vacuuming my own floors. Sometimes it will randomly work and empty itself as well. We also constantly get errors that the roomba is stuck and when we go looking for it, we find it in the middle of the floor, not obstructed by anything, just stopped. It seems to error when finding home and just die quite a bit too. Overall, after seeing how great it did for only a short period of time, I would not spend the money on this brand name again. I’ve tried to submit a ticket for this on the app a couple of times only to have it error before submitting after I spend time typing all of this up. What a waste of $300. Save your money. This isn’t any better than the many other brands that are out there, but it definitely costs more. In fact, I talked a friend into buying a roomba during the first few blissful months when we loved it. I followed up with her recently and it turns out they returned it in less than a week because they too were getting constant errors, so this doesn’t appear to be unique. The whole idea is that it takes care of a chore so you don’t have to. But be prepared because you have a new chore now. Vacuum mechanic and locator. I have been in touch with customer care. They sent me a new clean base and the problem was solved, or so it seemed. Then the vacuum began getting itself lost and not returning home and giving location errors again. I reached back out to customer service and they opted to replace the actual vacuum. While I was waiting for that vacuum, the clean base stopped emptying again, which was the problem I originally complained of. I figured I’d wait to complain until I could see if the new vacuum fixed it. Well, the new vacuum came with its own set of errors. Now it’s telling me the clean base is clogged (it’s brand new and I have checked it for a clog and there is none). It also gave me an error that the bag was full but it’s a brand new bag and not full. I’m over this vacuum. The only good thing about it is that they’re trying to solve my problem however a new problem continues to pop up each time. And since the clean base is new and a separate vacuum was also sent to me brand new, this appears to just be a bad product.im frustrated because at this point, I’d like to mail the vacuum back for a refund but am told that I only had 30 days to do that so basically I’m stuck. Update. In 4 months we will have had this $400 piece of junk for 2 years, so it’s been just over a year and a half. The bin has NEVER emptied consistently and often doesn’t even alert us that it needs to be emptied so we think it’s working fine until we can’t get it to work one day and find the bin jam packed. We still consistently get random errors. We are unable to use “vacuum everywhere” because when we do, it just hops off the base, vacuums for 5 minutes and claims to have completed the job successfully. Now, it has stopped operating completely. We open the app and it says it needs to be rebooted but then the reboot doesn’t help. As soon as it comes back online it claims to need to be rebooted again. It won’t run. It won’t do anything. Absolute waste of money. I will never purchase Roomba brand again.

Have had the Roomba 105 system with dock & self-empty features for over a year and after a few setup gotcha's - Have been more than satisfied. I use it several times a week in high traffic areas and would consider it 90% as effective as a traditional vacuum cleaner. Works on short and shag carpet as well as hardwood and vinyl flooring. Small items like throw rugs, loose clothes, toys, need to be moved first to prevent getting caught underneath Roomba - but not really a big deal. Cleaning the unit periodically is important (videos show part of this process) but well worth the effort every month or so under heavy use. Few things I've learned: - It's important to take your time during the initial house/room mapping setup part of the Roomba Home app. I rushed through it thinking just telling it to map the whole house & run that each session was ok but found that it was not practical. After the initial mapping is complete you really need to further edit/separate the individual rooms to have the flexibility to just clean the high traffic areas most frequently. In my case the kitchen and family room are the biggies. There are also other clean management features available in the app like spot clean, auto program clean sessions, vary between light, standard, and heavy clean times -- however, I keep it simple just using standard clean and managing the individual rooms. - Keeping the unit itself clean around the dust bin, brushes, external sensors etc. is important (Once a month or so with moderate use) replacing filter and brushes also as needed. - I've had rare instances of Roomba seeming to 'glitch' during a cleaning cycle or the app seeming to hang and have the fix to be reset the system with the 10 second hold on the power button. WiFi Internet access glitches can also cause this. - Overall for me this has been a great product and big improvement from dragging that old upright vac and its cord all over the house. Probably not right for everyone but I can definitely recommend.

I got this guy for Black Friday after months of research and over analyzing. It is our first robot vacuum and we have been dreaming about one for a long time. It has been about a month since his inaugural run and I have to say I love him just as much, if not more, than I did that first day. He is a little noisy but his running noise is very easy to ignore and not distracting, even if you are in the same room, and both my husband and I have some auditory sensitivities. The self empty 100% sounds like a jet taking off. It isn’t so loud that it affects me in my home office two rooms away, but it is in our den and it is definitely “pause the tv” loud in the den. However the self emptying process takes maybe about ten seconds so is very easy to work around. We have two dogs and two cats. One of those dogs is a Great Pyrenees so it is basically like having five dogs. One of our cats is a Maine coon mix so lots of very downy fluff floating around, mixing with the great white Pyr tumbleweeds. This little guy does so well with all the fur. Obviously we do need to keep an eye on the spinning sweeper and the rollers but their maintenance is lower than any previous vacuum so we are very happy. Both my husband and I grow our hair out to donate so there is a lot of long hair floating about and again our little guy is excellent with the lightest of maintenance. As previously mentioned we have two cats so kitty litter is a thing, we also have a “flinger” so despite our best efforts it does travel quite a bit, until it is time for him to make his run, then it is gone! He has done well on our wood floors, our stone floors, he even does well “off roading” on our brick fireplace. Our rugs look great too. I will say our only real struggle is our high pile carpet in our living room. It is an inherited home and that carpet is an area we have not gotten to renovating yet, so it is old, dirty and very plush. Think almost shag carpet but thicker. He definitely struggles to take care of it, trying to roll through all that fluff and trying to suck up accumulated dust, etc. from all that fluff, he almost always needs to take a little break to recharge before he completes the room. (Me too bud, me too!) However, he does make it through and it does look better than it has in years, so he is still doing a great job. With all that he has to tackle we have him scheduled to run twice daily and occasionally we will skip a run or block off rooms that have not been used. It would obviously be cool to have the options the other roombas have to create keep out zones or have specific tasks for them to do but it has not been that difficult to block off rooms or shut doors if need be. If he doesn’t have to tackle the living room carpet he can do his whole run without needing to recharge. I can not speak highly enough about how this little addition to our family has improved our life. To be rushing around to get ready for the tiny Christmas company we got to have, and have our little buddy running around helping, I can not explain how much of an impact that makes on our home and our mentality. This is not the perfect robot vacuum but for the money, he is above and beyond perfect for our family. Will definitely be a roomba “parent” for life! 😂

I had a really old roomba vacuum that lasted me many years. It was time for a replacement, and I was excited for the innovation that has happened in ten years since I last bought one. It was a breeze to set it up after it arrived. There is a qr code you can scan to download the app. Once I did that, it walked me through setup. I pop on the brush, plug in the auto empty dock, and got it on my wifi. Then it sets up a map. This photo is just after it returned to the dock after doing the map. It was impressive and fast how it mapped out the floor, and I love how it automatically goes back to the dock. Then I let it vacuum. I had let it get kind of "crumby" so really see it in action. After it vacuumed, the floor felt "crumbless" and clean. I’ve been using it now for a little over a week, and its helping me keep the floor cleaning up with my two kids and busy schedule. I love that I can schedule cleanings or just start one with a tap on my phone. It did a good job navigating around furniture, under tables, and dodging the trash bag my kid was supposed to have taken out that was sitting in the hallway by the door. It also goes over my thin rug and didn't get stuck. My regular one gets stuck and tries to suck that one up. The suction power is strong, and the dust bin seems simple to remove to empty but I haven't had to yet. The battery lasts long enough for the home. I have vinyl plank flooring throughout and its about 1200 feet. I’ve run it both during the day and while kids were sleeping. It didn't interrupt anything because its reasonably quiet. This has made a huge difference in keeping my floors cleaner in between deep clean mopping days. If you’re someone juggling work, family, or pets, this is a smart investment.

I bought this product with good expectations because I thought it would work better as part of my routine. I had heard good things about this type of supplement, so I decided to give it a try, expecting a more positive experience. After using it, honestly, it did not work the way I thought it would. In my case, I did not notice the kind of performance that would make me want to keep buying it, and that matters when you are looking for something you can actually feel good about using daily. On top of that, it felt expensive for what it ended up offering. Being honest, I did not like its performance, and that is why I give it 3 stars. I would not call it terrible, but it definitely was not a satisfying purchase for me. It just did not meet my expectations.
